UNITED STATES TBUSTIN C. HICKS, OF PITTSBURGH, PENNSYLVANIA.

HAND DISHWASHING MACHINE.

Application flled'li'ovember 15, 1921. Serial No. 515,374.

a citizen of the United States, residing atv Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Hand Dishwashing Machines, of which the following is a specification.

This invention relates to dish-washing machines, and more'particularly to a machine which is specially" adapted for supporting the dishes and similar articles in such manner as to permit the same to be acted upon to the best advantage by a' spray of washing fluid.

One of the main objects of the invention is to provide a device of the character stated of very simple construction which may be readily produced and sold at relatively small cost. A further object is to provide means for supporting plates and similar articles of chinaware at such an inclina ion as to be readily acted upon by the spray streams, this supportin means being adapted to accommodate p ates and similar articles of varying sizes.

sition at such an inclination as to permit the same to be readily acted upon from beneath, as well as above, bythe spray streams for effectually removing all foreign materials. the detailed description.

In the drawings Figure 1 is a front view of the washer;

Figure 2 is a top lan view;

Figure 3 is a section taken substantially on line 33 of Fig. 2;

Figure 4 is a section taken substantially on line 4:4 of Fig. 2;

Figure 5 is an underneath view of the sprayer and associated parts which I prefer to use in connection with my machine.

The machine includes a boxlike casing 1 of sheet metal whch is supported b feet 2 of angle cross-section. At one an of the casing I provide a top plate 3 which cooperates with the front and back walls 4 and 5, and the adjacent end wall to form an enclosing hood 6 open at its inner side. Within this hood, at each end thereof, are secured two angle brackets 7 which are inclined upwardly and inwardly of the casing and are 55 ,disposed at an angle of 45 to end wall 8.

Further objects will appear from A supporting member or shelf 9 of reticulated construction is supported by each pair of brackets 7 and extends transversely of the casing 1 These shelves serve to support cups, glasses, and similar articles in an im verted position and inclined at an angle of 45 so as to permit ready washing of the same by a spray member inserted into the casing and moved about so as to direct a spray onto the articles to be washed. In this connection, I have found by extensive experiments that an angle of approximately 45 is the most effective angle at which the shelves 9 can be -su ported. During the washing operation 0 the articles upon the shelves, the hood 6 serves to efi'ectually prevent splashing of the water or washing solution outside of the casing 1.

To permit ready manipulation of the sprayer, front wall t of casing 1 is cut away from its upper edge to provide an opening 10 by means of which the sprayer can be readi inserted into the casing and manipufate so as to direct the spray upon the articles to be washed. At the opposite end of easing 1 from shelves 9 I provide a rack 5 11 for su porting plates, saucers, and similar artic es. This rack includes substantially U-shaped and frames 12 which are connected by brace bars 13, each of these frames having the lower end of its end ar|n13 turned inwardly to provide a foot 14. For supporting the plates and similar articles on ed e I provide a plurality of spaced parallel coils 15 of wire or other suitable material, these coils being secured to the rack 11 and the convolutions of the coils being spaced a comparatively great distanceapart. These coils provide simple and efiicient means whereb the plates and similar articles may be rea ily supported on edge at an inclinationtransversely of casing 1 and also at an inclinationto the vertical, so as to be acted upon to the very best advantage by a spray directed onto the plates from a sprayer inserted into casing 1 throu h opening 10. Also, the coils 15 will readi y accommodate lates and similar articles of unusual size 3; placing the plate at a considerable inclination transversely of casing 1, this bein possible due to the provision of the coi members the convolutions of which are spaced apart, as previously described. A cylindrical container 16 of; woven wire construction is placed in casing 1 adjacent to the inner end of rack 11. This container is adapted to receive knives, forks, spoons and similar articles to be washed.

Bottom 11 of casing 1 is provided with a central longitudinally extending trough 18, and with discharge openings 19 communicating with this trough adjacent to each end of the casing. Opening 19 dischar es into a downwardly and outwardly inc ined discharge spout 20 secured to the underfaoe of the bottom of the casing. In practice, the casing l is placed upon a draining board adjacent to a sink, so as to be inclined downwardly toward the sink, and the upper opening 19 is closed bya suitable stopper or plug. During the washing operation, the washing solution and the moved from the dishes flows into trough 18 and is discharged through opening 19 and spout 20 into the sink. After the dishes have been washed by means of a soap or other suitable solution sprayed onto the same, they may be readily rinsed by spraying hot water onto the dishes, after which they can be either wiped by hand or rmitted to set in casing 1 until they'have ried. l

I prefer to use a sprayer, such as that illustrated in Figure 5, which is provided with a body 21 for reception of a suitable detergent, this body being provided at one end with a neck 22 for reception of a suitable hose 23 provided with a connector 24 of any suitable or preferred type by means of which the sprayer may be connected to a faucet; At its other end body 21 is rovided with a spray-head 25 having a p urality of spray openings 26 which are directed radially of the head and are disposed in alignment axi; ally thereof. The body 21 is closed by a suitable lug 27 or in any other suitable or prefer manner, so as to permit ready introduction of the deter ent into the body. As will be understood, t e sprayer operates within casing 1, through opening 10, the spray head 32 being moved about so as to direct the washing solution over the articles to be washed to the best advantage. By

articles of food etc., re-- a casi turnin the sprayer So as to direct the spray beneat shelves 9 the cups and other hollow articles placed upon these shelves may be readily washed. The casing 1 18 so constructed, and the shelves 9 and rack ll are so arran ed, as to permit the spray to be readil directed beneath the shelves, theinclinationof the shelves being such that the lower shelf does not interfere in any way with directing the spray beneath the upper shelf and into the cups and other articles supported thereby.

The machine constructed in the manner above described and found by ektensive experiments to be highly eflicient, and can be readily produced and sold at small cost, being specially adapted for use in the average household.

What I claim is 1. In a device of the character described, open at its top and constructed at one en to form a hood opening into the casing, said casing having one wall cut away so as to permit a spraying device to be introduced into and manipulated within the casing, means within the hood for supporting cups and other open articles, said means being of open construction, and means remote from said supporting means for supporting dishes and similar articles to be acted upgn by a spray, the lastmentioned means ing of open-work construction, said casing being provided with outlet openings.

2. In a device of the character described, a casing o n at its top and constructed at one end to orm a hood, shelves of reticulated construction supported within the hood and disposed at an upward and inward inclinatio'n relative to the casing,and a rackadapted to support plates an similar articles in position to be acted upon by a spray, the front wall of the casin' being cut away to permit a spraying mem er to be introduced into and manipulated within the casing.

In testimony whereof I alfix my signature.
